APHIS¹ Wildlife Services (WS) unit has a detector dog program in cooperation with the Department of Defense. The dogs in this program, usually Jack Russell terriers, are trained to sniff for brown tree snakes in aircraft, vehicles, household goods, and ships leaving Guam for snake-free areas like Hawaii, the Mariana Islands, and Saipan. Brown tree snakes have infested the island of Guam, causing the extinction of several native species of birds. To protect the rare flora and fauna in Hawaii, it is important to avoid accidentally introducing this destructive pest into the environment. Currently, 14 detector dogs and their handlers prowl the airstrips and piers of Guam searching out hitchhiker snakes. WS also provides information, guidance, and expertise to ranchers interested in using livestock-guarding dogs, which can be trained to protect sheep from predators. WS has several livestock-guarding dog experts on staff and can provide detailed printed material that outlines how to set up a livestock-guarding program. These various APHIS programs illustrate that different kinds of dogs are best suited to do different types of jobs.
